Specification of Letters Patent.

Application filed June 9, 1914. Serial No. 843,989.

To all whom it may concern.'

Be it known that l, WILLIAM R. MARsDEN, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and lmproved Pressed-Metal Door and lVindow Sash, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved pressed metal window sash which is strong and durable, comparatively cheaper to manufacture than solid steel and sectional hollow metal sashes Aas now constructed, which is exceedingly light to permit easy and accurate counterbalancing, and is readily adaptable for use in dwellings, factories, office buildings, banks and other structures.

ln order to accomplish the desired result. use is made of a single piece of sheet metal having hollow stiles and hollow top and bottom cross bars, the stiles and cross bars having jointless outer faces. Use is also made of muntin plates merging at their ends with the stiles and cross bars, the muntin plates having integral flanges, and muntin bars each having a base seated on a corresponding muntin plate and held in position thereon by the flanges of the muntin plate.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a cross section of a window provided with metal upper and lower sashes; Fig. 2 is an enlarged face view of a portion of one of the sashes looking at it f" from the inside of the window; Fig. 3 is a sectional plan view of the same on the line 3 3 of Fig. 2; Fig. 4 is an outer face view of the same; Fig. 5 is a sectional plan view of the two muntin bars at their point of intersection, the section being on the line 5-5 tom cross bars A2, A3 and.intersectingbars A4, A5, of which the bars AAL connect the side bars A, A1 with each other at points intermediate the bars A2, A3, and the bars A5 intersect with the bars A4A and connect with the bars A2 and A2 intermediate the bars A and A. The several bars at their junctions have portions cut out as at AG and A7 to allow of pressing the blank in a suitable machine with a view to form hollow stiles B, B, top and bottom cross bars C, C and horizontal and vertical muntin plates D and D. Each of the stiles B and B has its edges interlocked to form a seat B2 extending along the inner side of the corresponding stile, and the top and bottom cross bars C, C have similar inter-locked edges having seats C2 merging with the interlocked edges B2 thus providing a continuous seat for the window pane `putty F, and which also are adapted to receive and hold muntin bars G and G', each made from a strip of sheet metal doubled up to form a shank G2 terminating at one end in a head G3 and at the other end in a base G4 fitting between the flanges D2, D3 of the corresponding muntin plate D or D. It is understood that the muntin bars G and G" are placed in position on the bars A, A5 prior to pressing the said bars into the form of muntin plates so that the. muntin bars are fastened in position on the muntin plates during the process of pressing the muntin plates into shape together with the stiles B, B and the top and bottom cross bars C, C. The muntin bars G and G at their points of intersection pass one over the other, as will be readily understood by reference to Figs. 5 and 6.

It will be noticed that by constructing the window sash in the manner described, the stiles, cross bars and muntin plates are formed from a single piece of sheet metal and the separate muntin plates are firmly fastened in place during the process of shaping the stiles and muntin plates, and a sash frame thus made forms a continuous seat for the window panes E which can be readily secured in place with putty F in the usual manner. In practice, portions of the putty are used intermediate the panes E and the interlocked edges D2 and flanges D3 of "lil the stiles, the top and bottom cross bars, and muntin plates. It will be noticed that the panes if broken can be readily replaced by new ones without disturbing any part of the sash frame. By having the muntin plates forming integral parts of the stiles and cross bars, they form strong braces for the stiles and cross bars. The abutting end portions of the stiles, cross bars, muntin plates and connection bars, which are not continuous, are preferably soldered or brazed together.

It is understood that the sheet metal used for forming the sash frame is selected as to gage and quality to permit of readily pressing it into shape without fracturing it. If desired the muntin plates and muntin bars can be omitted and the sash frame formed of continuous stiles and cross bars only.

Although in the foregoing a window sash is described it is evident that a door may be made in the same manner and hence I do not limit myself to the window sash or to any special sheet metal of which the sash or door is made.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

l. A door and window sash comprising a single sheet of metal, said sheet having a plurality of rectangular openings in it, and slitted in the corners of each of the openings and at the corners of the sheet, forming thereby a plurality of bendable flanges, the marginal flanges of the sheet being bent around to form hollow rails and stiles and having the edges of the sheet interlocking with a plurality of the bendable flanges, the flanges surrounding the openings being doubled over to form muntin plates.

2. A door and window sash comprising a single sheet of metal, said sheet hav-ing a plurality of rectangular openings in it, and slitted in the corners of each of the openings and at the corners of the sheet, forming thereby a plurality of bendable flanges, the marginal flanges of the sheet being bent around to form hollow rails and Stiles and having the edges of the sheet interlocking with a plurality of the bendable flanges, the flanges surrounding the openings being doubled over to form muntin plates, and muntin bars embraced by said muntin plates.

3. A door and window sash comprising a single sheet of metal, said sheet having a plurality of rectangular openings in it, and slitted in the corners of each of the openings and at the corners 0f the sheet, forming thereby a plurality of bendable flanges, the marginal fianges of the sheet being bent around to form hollow rails and stiles and having the edges of the sheet interlocking with a plurality of the bendable flanges, the flanges surrounding the openings being doubled over to form muntin plates, and muntin bars having a base embraced by said muntin bars.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

WILLIAM R. MARSDEN.
